Abstract:
In the title compound, C14H9ClN2O3, the fused pyridine and isoxazole rings are approximately planar, making a dihedral angle of 1.14 (16)°. The mol-ecule is twisted with the benzene ring and the mean plane through the fused pyridine-isoxazole ring system being inclined to one another by 47.03 (13)°. There is an intra-molecular O-H⋯O hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains propagating along [001]. The chains are linked by slipped parallel π-π inter-actions, involving inversion-related benzene rings, forming slabs lying parallel to the bc plane {inter-centroid distance = 3.770 (2) Å].

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
